Depression causes lack of appetite. The cat will be less active, sleep more, will be aggressive, easily irritable and sometimes extremely vocal. Depression may be caused by loss, lack of attention from the owner, hormonal imbalance or a disease. Depression can be treated with mild antidepressants.
Pain and internal obstructions, amongst other factors, can cause the affected cat to lose its appetite entirely. Anorexia can also be due to a psychological problem, such as overwhelming stress, major changes in routine, and environmental or dietary changes. Other causes include: 1  Aging. 2  Cardiac failure. 3  Toxicities and drugs. 4  Tumor (mass of growth).
